The water-tight mechanism of the steel reinforced concrete spigot and socket pipe relies primarily on the elastic compression of the "O" type rubber gasket between the interfaces. The raw material for the water stop belt in the concrete structure spigot sockets is currently a more advanced Larmier rubber water stop ring, which possesses excellent anti-seepage properties. As the interface method of the concrete structure spigot pipes, which uses rubber sealing rings, is all soft interface, the steel reinforced concrete spigot and socket pipes allow for slight bends or minor horizontal displacements at the joint location, enabling them to fit into pipelines that have uneven bends or slight deformations between joints.
